Network Protocol Analyzer
 Takács, Tamás ; Žádník, Martin (referee) ; Tobola, Jiří (advisor)
Bachelor's thesis describes an implementation of a network analyzer with an easy graphical web interface. Network Analyzer captures network communication and allows the detailed analysis. Its main task is to monitor data flows and identify protocols, which are situated on application-layer model TCP / IP. Thesis describes two types of possible identification of application protocols, which are based on the port number and the payload content TCP packet / UDP datagram. Web interface provides an overview of the output values of the network analyzer.

Network attacks by Cain & Abel
 Smékal, Lukáš ; Stančík, Peter (referee) ; Sobotka, Jiří (advisor)
This Master’s thesis is dealt in the local area network security, cryptographic algorithms, particular attacks on computer networks a practical application these attacks in local area networks. To application particular attacks is used the Cain & Abel program. The detailed manual for this program is created from the results of these attacks. This manual contains the exhibits of usage particular program tools and the attack application exhibits. This manual considers consequences of particular attacks and summarises achieved results during work with tools too. Master thesis closely deals with one of the program tools called RSA SecureID Token Calculator. Authentication via hardware tokens is contained in this Master thesis. Thesis contains the way of authentication using RSA SecureID Token Calculator without physical owning of the hardware token. Cain & Abel program shows and interprets why cashed passwords in operation system are dangerous and it shows methods how attacker can reveal this passwords from the operation system memory. This Master thesis is focused on sniffing credentials and passwords in local area networks and it is focused on cryptographic algorithms cracking for username and passwords revealing.
